Based on Chirp Spread Spectrum modulation technique (CSS)
Technically speaking…
-
LoRa uses sub-gigahertz radio frequency bands
-
Data rate 0.3 kbit/s and 27 kbit/s depending on spreading factor
-
LoRa is the physical layer, LORAWAN is MAC Layer
-
LORAWAN acts mainly as a network layer protocol for managing communication
